(1976) Quincy Steel Casting Company, Inc., North Quincy, Massachusetts. (Click to open report) A health hazard evaluation determination conducted at the Quincy Steel Casting Company (SIC-3321) revealed potentially toxic exposures to crystalline silica (7631869) and iron oxide. Excessive silica exposures were found in all areas of the foundry and cleaning room, while iron oxide exposures occurred throughout the cleaning room and torch cut-off operation. Potentially toxic exposures were not found for lead (7439921), manganese (7439965), zirconium (7440677), fluoride, p,p'-diphenylmethane-di...

(1976) Republic Steel Corporation, Cleveland, Ohio. (Click to open report) A Health Hazard Evaluation investigation was conducted by NIOSH on August 5 and 6, and on December 4, 1975, in the 45-inch slab mill area (SIC-3316) of the Republic Steel Corporation plant, in Cleveland, Ohio. The survey was prompted by a request from an authorized representative of the 10 affected employees to evaluate potential hazard to crane operators.

The survey was prompted by a request from an authorized representative of the 10 affected employees to evaluate potential hazard to crane operators. Environmental sampling revealed that the crane operators were not exposed to harmful concentrations of dust or oil mist in their job as it was performed at the time of evaluation. It is felt however, that since high temperatures were recorded in the crane cabs, that an evaluation should be made of crane operators exposure to heat stress. Due to the possible harmful concentrations of oil mist in the crane cabs, as well as the potential synergistic effect of other contaminants and heat, it is recommended that crane operators and supervisory personnel should be informed of the importance of the cranemen having adequate time away from the crane cabs.

Silicone Corporation, (SIC-2821) Division of the Stauffer Chemical Company in Adrian, Michigan was investigated on January 28 to 29 and April 6 to 7, 1976. The investigation was requested by an authorized employee representative. Area sampling and nondirected medical interviews were conducted during the first visit. Half of the 35 employees originally interviewed reported health problems. All but two of the silica (7631869) powder or mica (12001262) air samples were below recommended criteria of 3 milligrams per cubic meter and 20 million particles per cubic foot, respectively. Particulate concentrations were generally greater in the HCR area. Skin rash, upper respiratory irritation and congestion, colds, nasal sores, short breath, wheezing, and coughing were among the symptoms reported by the workers. The authors recommend that high efficiency particulate be used in the mixing operation and that workers use protective clothing and gloves.

(1976) Wheeling Pittsburgh Steel Corporation, Steubenville, Ohio. (Click to open report) Exposures to coal-tar-pitch, iron-oxide (1345251), carbon- monoxide (630080), silica (7631869), graphite (7782425), manganese (7439965), calcium-oxide (1305788), and dust were investigated in various work areas of the Wheeling Pittsburgh Steel Corporation (SIC- 3325) in Steubenville, Ohio on April 25, 1974. From April 29 to May 1, 1975 a follow up sampling was conducted for respirable particulates in the stockhouse and cast floor areas. The evaluation was requested by an authorized representativ...

From April 29 to May 1, 1975 a follow up sampling was conducted for respirable particulates in the stockhouse and cast floor areas. The evaluation was requested by an authorized representative of an unspecified number of employees. Personal and area air samples were collected by 10 millimeter nylon and 0.5 inch steel cyclones, respectively, and these were analyzed using the x-ray diffraction technique. Total dust samples of iron-oxide and free silica were obtained using closed faced three piece cassettes with filters which were measured gravimetrically for weight gain. The 1974 free silica personal air samples contained three exposures in the blast furnace area 4 times over the OSHA standard of 100 micrograms per cubic meter and 2 exposures in the stockhouse were 21 and 28 times over the federal standards. One crane operator was exposed to a nontoxic level of iron-oxide. Area samples were negative and carbon-monoxide, sulfur- dioxide (7446095), and iron-oxide were below detectable limits. The 1975 study for free silica in area sampling was negative in the cast floor and stockhouse. Exposures of 7 of 36 cast floor workers and 1 of 17 stockhouse workers were equal to air in excess of the NIOSH recommended free silica standard of 50 micrograms per cubic meter. Over half of all the samples were in excess of this NIOSH standard for exposure to free silica. The author concludes that both factory areas may expose workers to potentially toxic concentrations of respirable free silica. The author recommends medical screening of potential employees, medical examinations every 3 years, safety training, posting exposure areas, personal respirators, hygienic practices, and air monitoring.

(1975) Armstrong Cork Company, Jackson, Mississippi. (Click to open report) Exposure to airborne chrysotile asbestos in excess of the proposed OSHA standard of 0.5 fiber per cubic centimeter is found in a section of the Armstrong Cork Company (SIC-2499), Jackson, Mississippi, manufacturers of vinyl asbestos tiles. The potential for worker exposures to vinyl-chloride monomer is demonstrated for operators throughout the process, although all levels are found to be less than the existing OSHA standard of 1.0 ppm for vinyl- chloride (75014).

The potential for worker exposures to vinyl-chloride monomer is demonstrated for operators throughout the process, although all levels are found to be less than the existing OSHA standard of 1.0 ppm for vinyl- chloride (75014). Levels of toxic particulates including heavy metals and free silica are found to be below hazardous levels. Recommendations include improved enclosures, increased ventilation, and regular maintenance of local exhaust systems at material dump stations; approved respiratory protection for exposure to asbestos and vinyl-chloride, and periodic environmental and medical monitoring of operations and employees.

However, triethylamine concentrations are potentially toxic in the immediate vicinity of the one core blow machine used for this cold box process. This is also true of free silica (7631869). Potentially toxic concentrations of free silica were found in the immediate vicinity of the bucket elevator, but not in the operator's breathing zone.
